Description Josh Bressers 2007-12-19 07:50:25 EST
It was reported to secalert@redhat.com that the autofs defaults do not set the
nodev NFS option.

bug 410031 notes the missing nosuid option by default for the /net autofs
filesystems, the fix for that issue did not take into account that there was
also a missing nodev option for these filesystems.

Without the nodev option, it is possible for an attacker to mount a remote
filesystem which could give them access to various devices that should normally
have restricted access, such as /dev/mem, and various hardware devices.

Red Hat would like to thank Tim Baum for reporting this issue.
